when using the hatch tool, firstly we need to select a 'closed contour' or a boundary, once selected QCAD dynamically shows us any loops that are not closed.However only one loop is shown at a time. It would be good if QCAD could show all loops that are not closed in one go or maybe some additional options could be added...

An additional suggestion to this problem - to 'Zoom' to a particular 'loop not Closed' coordinate position.It would be time saving to have this option in the View tools to zoom to a particular coordinate . Then I could copy a 'loop not Closed' coordinate location from the command line and paste it into a field and hey presto zoom straight to this location, oh I hope this makes sense here what I'm trying to explain This would sure save a lot of time especially when I have a lot of entities in my drawing!
